A packaging material for a power storage device, comprising at least: a substrate layer; a metallic foil layer with an anti-corrosion treatment layer being disposed on one face or both faces thereof; and a sealant layer in this order, wherein the sealant layer includes a polypropylene-based resin (A) and 1 to 40% by mass of incompatible component (B), and maximum seal strength S.sub.M in an adhered portion resulting from adhesion by heat-sealing the packaging material is 35 N/15 mm or more, and in addition, the packaging material for a power storage device satisfies the following requirements (1) or (2): (1) a ratio S.sub.S/S.sub.M of seal strength S.sub.S to maximum seal strength S.sub.M in a stable range is 0.3 or more; (2) a ratio S.sub.A/S.sub.M of average seal strength S.sub.A to maximum seal strength S.sub.M is 0.3 or more.

A method for providing a miniature electrochemical cell having a total volume that is less than 0.5 cc is described. The cell casing is formed by joining two ceramic casing halves together. One or both casing halves are machined from ceramic to provide a recess that is sized and shaped to contain the electrode assembly. The opposite polarity terminals are electrically conductive feedthroughs or pathways, such as of gold, and are formed by brazing gold into tapered via holes machined into one or both ceramic casing halves. The two ceramic casing halves are separated from each other by a metal interlayer, such as of gold, bonded to a thin film metallization layer, such as of titanium, that contacts an edge periphery of each ceramic casing half. A solid electrolyte of LiPON (Li.sub.xPO.sub.yN.sub.z) is used to activate the electrode assembly.

A quick change battery clamp includes a first clamp body, a second clamp body, and a handle assembly. The second clamp body is coupled to the first clamp body. The handle assembly is selectively disposed through each of the first clamp body and the second clamp body. Each of the first clamp body and the second clamp body define an aperture having a substantially polygonal cross-section configured to receive a battery post. Each of the first clamp body and the second clamp body have an internal wall with a plurality of ridges configured to selectively abut the battery post. The first clamp body and the second clamp body are hingedly connected.

A battery, a battery module, and a battery pack are provided. The battery includes a cell and a casing. The casing accommodates the cell. The cell includes a cell body, a first insulating film and a second insulating film. The first insulating film is disposed on a surface of the cell body and covers a part of the surface of the cell body. The second insulating film is disposed to be independent from the first insulating film and is partially adhered to a surface of the first insulating film away from the cell body, and is partially adhered to the surface of the cell body that is not covered by the first insulation film. The first insulating film is fixed firmly to the cell body.

A wiring module to be attached to a plurality of power elements which store or generate power includes a bus bar connecting the power elements to each other or connecting the power element and a load to each other, an abnormality detection element detecting an abnormality of the power element, and an insulating protector holding the bus bar and the abnormality detection element. The insulating protector is integrally provided with a first holding shaft portion and a second holding shaft portion which position and hold the bus bar by fitting the bus bar there onto, and an element holding portion which position and hold the abnormality detection element by fitting the abnormality detection element there into.

A rechargeable battery pack supplies electrical drive power to an electrically driven machining device. The rechargeable battery pack has: a plurality of rechargeable battery cells, wherein the rechargeable battery cells each have cell contacts; a housing, wherein the rechargeable battery cells are arranged within the housing; and a potting compound, wherein the potting compound protects the cell contacts from contact with water from outside the housing. The housing has a housing top part and a housing bottom part. The housing bottom part overlaps the housing top part such that the housing top part defines an outer region and an inner region of the housing bottom part for the potting compound. A casting level of the potting compound in the outer region is above a casting level of the potting compound in the inner region.

A rust inhibitor for a gasket, a gasket for a secondary battery including the same, and a secondary battery are provided. The rust inhibitor includes an anti-rust material and a polymer resin, wherein the polymer resin includes at least one of polyethylene or a copolymer which includes 2 or more derived units selected from the group consisting of an ethylene-derived unit, a propylene-derived unit, a butylene terephthalate-derived unit, an ethylene terephthalate-derived unit, and a methyl acrylate-derived unit.
